This protocol has been created to ensure effective co-operation between Competent Authorities (CAs) with respect to their obligations under Article 41 of MiFID (Suspension and removal of in-struments from trading).The purpose of the notification obligations under Article 41 is to afford investors across all Mem-ber States the same level of protection regardless of where they trade. In order to achieve this outcome, a shared understanding of the different circumstances under which trading may be suspended in different Member States according to their national law and the expected course of action under Article 41 is helpful. To ensure trading is suspended or an instrument is removed from trading in an effective and timely way, an effective communication process is necessary.The protocol will be kept under review in light of practical experience.
